What it does

Browser Automation is an agent skill from lamm-mit/scienceclaw. Playwright-based browser automation for scraping JavaScript-rendered scientific databases

Its SKILL.md is about 410 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `scripts/browser_fetch.py`).

It sits in Productivity & Automation, covering Browser automation, Web scraping and Browser testing. It works with Playwright and JavaScript. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit ab9aba1. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
- python3
- pip
- playwright
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- rcsb.org
- ncbi.nlm.nih.gov
- ebi.ac.uk
- alphafold.ebi.ac.uk
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Browser Automation loads about 414 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 69 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~27
When it runs · the whole SKILL.md, loaded when a task matches: ~414

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

name: browser-automation
description: Playwright-based browser automation for scraping JavaScript-rendered scientific databases

Overview

Web browser automation using Playwright for scraping JavaScript-rendered scientific databases, automating form submissions, and capturing dynamic content unavailable via static scraping. Renders pages fully (including React/Vue/Angular SPAs) and extracts clean text content.

Useful for databases that require JavaScript to display data, interactive tools that need form interaction, and pages where content loads asynchronously after the initial HTML response.

Usage

bash

# Fetch a JavaScript-rendered page
python3 skills/browser-automation/scripts/browser_fetch.py \
  --url "https://www.rcsb.org/structure/1TUP"

# Wait for specific element before extracting
python3 skills/browser-automation/scripts/browser_fetch.py \
  --url "https://www.ncbi.nlm.nih.gov/gene/672" \
  --wait-for ".gene-summary"

# Extract text content
python3 skills/browser-automation/scripts/browser_fetch.py \
  --url "https://www.ebi.ac.uk/chembl/compound_report_card/CHEMBL25/" \
  --extract-text

# Save screenshot
python3 skills/browser-automation/scripts/browser_fetch.py \
  --url "https://alphafold.ebi.ac.uk/entry/P04637" \
  --screenshot /tmp/p53_alphafold.png

Output Format

pip install playwright
playwright install chromium

Questions about Browser Automation

What does Browser Automation do?

Playwright-based browser automation for scraping JavaScript-rendered scientific databases. Browser Automation is an agent skill from lamm-mit/scienceclaw.

When should I use Browser Automation?

Browser Automation fits situations like: tasks that involve Browser automation; tasks that involve Web scraping; tasks that involve Browser testing.

How do I install Browser Automation in Claude Code?

Run `npx skills add lamm-mit/scienceclaw --skill browser-automation -a claude-code`. Or copy the skill folder (skills/browser-automation in lamm-mit/scienceclaw) into .claude/skills/browser-automation in your project. Claude Code loads it when a task matches its description.

How do I install Browser Automation in Codex?

Run `npx skills add lamm-mit/scienceclaw --skill browser-automation -a codex`. Or copy the skill folder (skills/browser-automation in lamm-mit/scienceclaw) into .agents/skills/browser-automation in your project. Codex loads it when a task matches its description.

Can I use Browser Automation in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add lamm-mit/scienceclaw --skill browser-automation -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/browser-automation, .gemini/skills/browser-automation, .github/skills/browser-automation and .opencode/skills/browser-automation in your project.

What does Browser Automation need to run?

Going by SKILL.md and its folder, Browser Automation needs Python for the scripts in its folder and the command-line tools its instructions call (python3, pip and playwright). Our summary lists: Python 3.

Does Browser Automation access the network?

SKILL.md names 4 domains. In commands or code: rcsb.org, ncbi.nlm.nih.gov, ebi.ac.uk and alphafold.ebi.ac.uk; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.

Is Browser Automation safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Browser Automation use?
